The value structure of Theo van Rysselberghe is mid-key: quiet, controlled, and cohesive. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 7.1%, #654129 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 62 units: broad enough to build convincing three-dimensional form. In the context of Theo van Rysselberghe's full range of palettes, group 11 represents one movement in an ongoing chromatic dialogue.
